good morning feizzinbee

i don't know if this will work but on the ramp going up instead of sand paper that may or may not sand the tire smooth and loose traction you may try using the paint that you use for the road and mix  some sand in it to make a little rougher just use it where the tires will be not where the steering arm will be may not ware the tires just a thought

Good suggestions both on curving the roadway and sanding the paint.   Kevin, I hadn’t considered that... but I’m not sure I could get as fine a grit in sanded paint as I did with the paper.   I used something like 400 grit paper so it’s just enough, and hopefully won’t tear into the tires too bad.    Alan, curving the road was my fallback plan if the simple ramp didn’t work.   Of a bigger concern than the slope was whether the car would bottom out when going over the (sharp) crest of the hill...  so far it seems ok, so long as my wheelbase isn’t too long nor the car too low.   

The video attached represents my progress as of a couple days ago.   The cars now stop for gas and complete the full circuit nicely.   Since this video was taken I’ve gotten more buildings connected to power, added a few details, and have the lights on that police car going .  More progress pics to come.

This is so cool that I might rip up all my 3-rail and build a roadway instead of a railway

The gas station stop is automated so that the second car bypasses the station? WOW!

Yes, it's a pretty slick set-up that is sold by AutomotionFX as a gas station kit.   The entry switch/turnout detects an approaching car and diverts it to the gas station path, and then a stop section holds the car in place for a predetermined amount of time (which is adjustable) before releasing it.   The switch is set up such that no other cars enter the gas station until the one at the stop sections is released.  A merge piece at the gas station exit allows the car to re-enter the flow of traffic when it leaves after a "fill-up"

The entry switch/turnout consists of a fist sensor, a solenoid controlling the switch, and a second sensor.   The stop section consists of a strong magnet connected to a rotating arm, which normally sits well below the track surface.  This magnet is rotated into place just below the road surface, on the passenger side of the car, when the stop section is activated.   Both pieces (the turnout and the stop) are controlled by a small logic module (which even has handy holes for mounting it under the layout surface) & the logic box has a small screw (25-step potentiometer) for adjusting the stop duration.

(1) When an approaching car passes the first sensor, the solenoid fires and diverts the wire guide toward the gas station.   It simultaneously also engages a magnet in the stop section, which which will stay active for a time duration set by the user.   

(2) When the car passes the second sensor, the solenoid is deactivated and the road reset to the nominal route, preventing any other cars from following the first into the gas station for the duration of the stop

(3) When the car arrives at the stop section, the engaged magnet activates a magnetic reed switch inside the car, causing the car's motor to stop and "pausing" the car

(4) When the timer expires, the magnet disengages (i.e. rotates away from the road surface and farther below the layout) and the car is released to rejoin the main road.  The turnout is then free to route the next car to the gas station.

 

As you can imagine, there are also other applications for this type of set-up - including having cars pause when merging into a roadway (via a stop control kit), having cars change lanes (or alternate lanes/paths), etc, that are already offered by AutomotionFX.   Looking into the future, it's not hard to imagine that with the proper logic box, and enough sequenced magnets, you could even have the cars queue up at red lights!

Again, excellent Dustin!  As I read, I was thinking of several scenarios.  A taxi or bus stop, The red light or stop sign scenario is definitely one that would be great!

Bob, it reminds me of the old Eldon slot cars we had as kids.  I still have the power pack, but my younger brother broke the pistol grip controllers and cars.  Mum threw them out, but I salvaged the power pack for train lighting and have never used it in 50 years since.
